Answer:
Instead of arginine codon, proline condon would be coded.
Explanation:
GCA encodes codes for glycine while on the other hand codon to GGU, GGC, or GGG encodes for glycine.
This substitution will lead to generation of complementary code “Proline” in the complementary mRNA or DNA strand.  
The codon CCT, CCC, CCA, CCG encodes for proline. If this mutation would not have occurred then Arginine would have been encoded in the complementary codon  with base structure of CGT, CGC, CGA, CGG
 
        
             
        
        
        
Answer and Explanation:
The ocean takes up carbon dioxide through photosynthesis by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water. It reacts with seawater, creating carbonic acid. ... In the center of the ocean, wind-driven currents bring cool waters and fresh carbonate to the surface.
